Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or
any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

Maximum Power Dissipation
The maximum safe power dissipation in the AD8146/
AD8147/AD8148 package is limited by the associated rise in
junction temperature (T
J
) on the die. At approximately 150°C,
which is the glass transition temperature, the plastic changes its
properties. Even temporarily exceeding this temperature limit
can change the stresses that the package exerts on the die,
permanently shifting the parametric performance of the
AD8146/AD8147/AD8148. Exceeding a junction temperature
of 175°C for an extended time can result in changes in the
silicon devices, potentially causing failure.
The power dissipated in the package (P
D
) is the sum of the
quiescent power dissipation and the power dissipated in the
package due to the load drive for all outputs. The quiescent
power is the voltage between the supply pins (V
S
) times the
quiescent current (I
S
). The load current consists of differential
and common-mode currents flowing to the loads, as well as
currents flowing through the internal differential and common-
mode feedback loops. The internal resistor tap used in the
common-mode feedback loop places a 4 kΩ differential load on
the output. Differential feedback, network resistor values are
given in the Theory of Operation section and Applications
section. RMS output voltages should be considered when
dealing with ac signals.
Airflow reduces θ
JA
. In addition, more metal directly in contact
with the package leads from metal traces, through holes,
ground, and power planes reduces the θ
JA
. The exposed paddle
on the underside of the package must be soldered to a pad on
the PCB surface that is thermally connected to a ground plane
to achieve the specified θ
JA
.
Figure 3 shows the maximum safe power dissipation in the
package vs. the ambient temperature for the 24-lead LFCSP
(57°C/W) package on a JEDEC standard 4-layer board with the
underside paddle soldered to a pad that is thermally connected
to a ground plane. θ
JA
values are approximations.
